SAMPLE lt'iACI-IINE.

Application filed February 17, 2923.

T at whom it may concern:

Be it known that VVrtnru: D. KIs'rLnn,

a citizen of the United States, and resident of the city of Sheridan,county of Sheridan, State of Wyoming, whose post-oflice address isSheridan, l Vyoming, has invented certain new and useful Improvements inSample Machines, of which the following is a specification.

The fundamental purpose of the present invention is to provide simple,efiicient and comparatively inexpensive sample extracting means designedprincipally for use in connection with apparatus for the milling ortreating of flour but which is capable of being used with equal facilityin connection with the manufacture or treatment of other materialswherein it is necessary or desirable that samples of the material beperiodically extracted for the purpose of inspection.

The foregoing and other important purposes and advantages of theinvention will be more readily appreciated by reference to J) thefollowing detailed description and accompanying drawings wherein I havedisclosed a preferred embodiment.

In the drawings,

Figure 1 is a view partly in vertical sec-- -"l tion and partly in sideelevation of my invention as it will appear in actual use.

Figure 2 is a top plan view of the construction disclosed in Figure 1,and

Figure 3 is a view similar to Figure 2 but showing certain parts in adifferent position.

Referring more particularly to these drawings, numeral 1 may be taken torepresent a. spout, conduit, or container to which the flour or othermaterial is delivered during the process of manufacture or treatmentthereof. As herein disclosed, the member 1 more closely resembles aconduit and, for the sake of convenience, is so termed in the followingdescription.

At a suitable point in its length the said conduit 1 is provided with aside opening 2. the effective area of which is variable through themedium of a sliding gate 3 movable in a suitable gateway 1 and adaptedto be secured in various adjusted positions through the inst-rumentalityof a. set screw 5.

A sample extractor, designated by the nu meral 6, is movable inwardlyand outwardly through the opening 2 and as herein disclosed consistssimply of a flat plate of suitable Serial No. 619,743.

width and length supported to move in a straight iine by means ofsuitable guidesT secured to the upper end of a sample box 8. The samplebox 8 is preferably secured to one side of the conduit 1 with the upperend of the box terminating flush with or in the plane of the lower edgeof the opening 2 so that the aligned edges of the box and open ing serveas a further support for the extracting member 6, in certain positionsof the latter.

The outer end of the extracting member 6 is secured to one end of a.connecting rod 9 having its opposite end fastened to the crank 10 of acrank shaft 11. The shaft 11 is mounted in suitable bearings 12 and 13carried by a supporting structure 14. At one end, the said shaft 11 isequipped with a belt pulley 15 adapted to be connected with the drivingmechanism of the apparatus for manufacturing or treating the materialdelivered to the conduit 1 so that the sample extractor 6 will be inconstant operation during the process of mainifacturing or treating saidmaterial.

In the use of the device the extracting member 6 is periodically movedinwardly and outwardly through the opening 2 by means of its connectionto the crank shaft 11. On the outward movement of the extracting member,the sample deposit accumulated thereon is engaged by a. suitable brush16, which serves to sweep said material into the sample box 8 and thisbrush is preferably supported by a. bracket member 17 extendingoutwardly from the conduit 1. The amount of sample material to beextracted from the conduit may be easily regulated by increasing thewidth of the extracting member 6 or by changing the position of thesliding gate 3 to increase or decrease the effective area of the opening2, the lower edge of said gate acting as a Scrapper to remove excessmaterial from the extracting member as shown to advantage in Figure 1.

lVhile I have described in the foregoing what I now consider to be thepreferred embodiment of my invention, it is to be understood thatvarious changes in the proportion and arrangement of parts may beresorted to within the scope and spirit of the appended claims.

I claim:

1. The combination of a conduit having a side wall provided with anopening and gateway formed between the inner and outer sides of saidvWall andcommunicat-' ing With said opening, agate slidable in saidgateway and adapted to pro eet into said opening to vary the effectivearea of" 2. The combination of a conduit having a vside wall providedwith an openmg'and a gateway formed between the inner and out er sidesof said Walland positioned above the opening 1n communication therewith,a sample receptacle secured QXtGllOllY to said arranged totravelinwardly and outwardly through said openingand sii'pported forsliding movement on the upper end of said receptacle, guide meanscarried by the re ceptaole andengaging said slide, a brush securedexteriorly to the said side 'Wall of the conduit and arranged toengagethe per surface of the slide and means for tuati ng the slide. r Y r Intestimony whereof l hereunto ai'fix signature,
